Abstract

A pyrotechnic composition includes a fuel, an oxidizer, flow and rate control agents and oleoresin capsicum as an irritant. The composition is useful in crowd control products. The composition contains rate control ingredients to maintain combustion at a temperature below the point of degradation of the oleoresin capsicum, balanced with a booster material to maintain combustion.

First claim

We claim:

1. A pyrotechnic composition comprising:
a fuel;
an oxidizer;
flow and rate control agents; and
oleoresin capsicum.

2. A pyrotechnic composition as set forth in claim 1 further including a booster material that includes:
(a) magnesium stearate; and
(b) a dry slurry powder that is made of approximately 10% to 20% silicon; 20% to 35% potassium nitrate; 1% to 15% carbon; 15% to 30% iron oxide; 5% to 20% aluminum; and 15% to 25% nitrocellulose.

3. A pyrotechnic composition as set forth in claim 2 wherein the dry slurry powder is made of approximately 15% to 18% silicon, 25% to 28% potassium, 2% to 5% carbon, 25% to 28% iron oxide, 10% to 15% aluminum, and 16% to 20% nitrocellulose.

4. A pyrotechnic, composition as set forth in claim 2 wherein a mixture including the fuel and oxidizer includes approximately 13% to 24% potassium chlorate, 3% to 22% baker's sugar, 6% to 22% magnesium carbonate, 20% to 40% terephthalic acid, 2% to 28% dye, 1% to 25% magnesium stearate, and 20% to 35% nitrocellulose.
